Selectively-activatable headwear retention device

ABSTRACT

Apparatus and associated methods relate to a retaining module coupled to headwear to selectively increase friction between the headwear and a user&#39;s head. In an illustrative example, the retaining module includes a coupling region coupled to an inner surface of the headwear. The retaining module may, for example, include an engaging region extending from the coupling region and including a retaining surface. The retaining module may be configured, for example, such that the engaging region is selectively operable between a stowed mode in which the retaining surface is substantially separated from the wearer&#39;s head by a portion of the headwear, and a deployed mode in which the retaining surface engages the wearer&#39;s head such that a coefficient of friction between the head and the headwear is increased relative to the stowed mode. Various embodiments may advantageously provide selectable levels of resistance to removal of the headwear.

This application claims the benefit of U.S. Provisional Application Ser. No. 63/162,677, titled “SELECTIVELY-ACTIVATABLE HEADWEAR RETENTION DEVICE,” filed by James P. Saadi, Jr., on Mar. 18, 2021.

This application incorporates the entire contents of the foregoing application(s) herein by reference.

TECHNICAL FIELD

Various embodiments relate generally to headwear.

BACKGROUND

People wear various forms of headwear for various purposes and in various environments. For example, people may wear headwear, for example, for practical, aesthetic, and/or ceremonial purposes. Headwear may, for example, take the form of hats, visors, headbands, scarves, crowns, or some combination thereof. Hats may, for example, include partially brimmed hats (e.g., caps), fully brimmed hats (e.g., fedoras, safari hats, bowlers), or non-brimmed. Hats may, for example, be soft (e.g., drivers caps, tam-o-shanters), hard (e.g., helmets, bowler's hats), or some combination thereof.

SUMMARY

Apparatus and associated methods relate to a retaining module coupled to headwear to selectively increase friction between the headwear and a user's head. In an illustrative example, the retaining module includes a coupling region coupled to an inner surface of the headwear. The retaining module may, for example, include an engaging region extending from the coupling region and including a retaining surface. The retaining module may be configured, for example, such that the engaging region is selectively operable between a stowed mode in which the retaining surface is substantially separated from the wearer's head by a portion of the headwear, and a deployed mode in which the retaining surface engages the wearer's head such that a coefficient of friction between the head and the headwear is increased relative to the stowed mode. Various embodiments may advantageously provide selectable levels of resistance to removal of the headwear.

Various embodiments may achieve one or more advantages. For example, some embodiments may advantageously retain headwear on a user's head during strenuous activity and/or adverse conditions (e.g., high winds). Some embodiments may, for example, advantageously allow a user to retain a hat on their head without unduly reducing an effective circumference of the hat (e.g., tightening the fit on the head). Accordingly, various embodiments may advantageously allow a user to wear a hat with a desired fit while still retaining the hat during otherwise adverse conditions and/or activities.

In some embodiments, in the stowage mode, a selectively activatable headwear retainer (SAHR) may be disengaged such that a user may advantageously don, adjust, and/or remove the headwear unencumbered by additional friction. In various embodiments, for example, the user-selectable stowage mode and deployed mode of the SAHR may advantageously enable a user to adjust their headgear quickly and easily to varying conditions. Accordingly, the SAHR may advantageously increase retention (increase resistance to removal of the headgear) as adverse conditions increase.

The details of various embodiments are set forth in the accompanying drawings and the description below. Other features and advantages will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

To aid understanding, this document is organized as follows. First, to help introduce discussion of various embodiments, a selectively activatable headwear retainer (SAHR) system is introduced with reference to FIGS. 1A-2B. Second, various configurations are discussed with reference to FIGS. 3A-3B. Finally, the document discusses further embodiments, exemplary applications and aspects relating to SAHRs.

FIG. 1A depicts an exemplary selectively activatable headwear retainer (SAHR) in an exemplary hat in a stowage mode. FIG. 1B depicts the exemplary SAHR of FIG. 1A in the exemplary hat in a deployed mode. FIG. 2A depicts a cross-section view of an exemplary SAHR 115 of FIGS. 1A-1B in a stowage mode. FIG. 2B depicts a cross-section view of the SAHR 115 of FIG. 2A in a deployed mode. A headwear 105 (e.g., a baseball-style cap, as depicted) is provided with an inner band 110. The inner band 110 may, for example, be secured at a lower edge such that the inner band 110 forms a pocket between a crown 106 of the headwear 105 and the inner band 110. In various embodiments the inner band 110 may, for example, be a sweat band.

A SAHR 115 is disposed within the headwear 105. In the depicted example, the SAHR 115 is disposed in a region of the crown 106 behind a visor 120 (e.g., a bill, a brim) of the cap (e.g., a front of the cap). The SAHR 115 includes a coupling region 125 and an engaging region 130. In the depicted example, the coupling region 125 is secured to the crown 106 by a seam 135. The engaging region 130 thereby depends from (e.g., hanging freely down), and is hingedly connected to, the coupling region.

In a deployed mode (shown, for example, in FIG. 1B and FIG. 2B), the engaging region 130 is deployed over the inner band 110 (e.g., on an opposite side of the inner band 110 from the crown 106). Accordingly, in the deployed mode the SAHR 115 is exposed such that it comes contact with a user's head (e.g., forehead) when the user dons the headwear 105.

In various embodiments the SAHR 115 may, for example, be at least partially formed of and/or coated with a friction-enhancing material. In various embodiments the friction-enhancing material may include, by way of example and not limitation, silicone, latex, rubber, polyurethane, neoprene, or some combination thereof. The friction-enhancing material may engage a user's head or other appropriate body portion. For example, the friction enhancing material may ‘grip’ a user skin, hair, clothing, or some combination thereof. Accordingly, the SAHR 115 may operate to advantageously retain the headwear 105 on a user's head during strenuous activity, adverse conditions (e.g., high winds), or some combination thereof.

Various embodiments may, for example, allow a user to retain a hat (e.g., headwear 105) on their head in a desired configuration (e.g., facing forward) even during activities and/or conditions (e.g., boating in stiff winds) which would normally require removal or reconfiguration (e.g., to be facing backwards). Various embodiments may advantageously allow a user to retain a hat on their head without unduly reducing an effective circumference of the hat (e.g., tightening the fit on the head). Accordingly, various embodiments may advantageously allow a user to wear a hat with a desired fit while still retaining the hat during otherwise adverse conditions and/or activities.

In a stowage mode (e.g., shown in FIG. 1A and FIG. 2A), the engaging region 130 is stowed (e.g., substantially entirely) behind the inner band 110 (e.g., between the inner band 110 and the crown 106). Accordingly, the SAHR 115 may be substantially concealed behind the inner band 110 such that it does not (substantially) engage a user's head (e.g., forehead) when a user dons the headwear 105. In the stowage mode, the SAHR 115 may be disengaged such that a user may advantageously don, adjust, and/or remove the headwear 105 unencumbered by additional friction. In various embodiments the user-selectable stowage mode and deployed mode of the SAHR 115 may advantageously enable a user to adjust their headgear quickly and easily to varying conditions.

In an illustrative example, a user may normally wear a cap (e.g., while walking in calm conditions, sitting, indoors) with the SAHR 115 in a deactivated status (stowage mode). The user may, by way of example and not limitation, quickly and efficiently selectively activate the SAHR 115 during conditions which may increase the risk of the headgear being unintentionally removed from the user's head (e.g., running, high winds, boating, jumping, climbing, crawling, riding in an open vehicle). The SAHR 115 may be easily carried with the user (e.g., stitched to an inner surface of the crown 106) and stored in a convenient location for selective deployment or stowage as the user desires, for example, based on current conditions and/or activities.

As depicted, the SAHR 115 is configured with a substantially uniform thickness. In various embodiments the SAHR 115 may be of different thicknesses. The SAHR 115 may, by way of example and not limitation, be relatively thin (e.g., approximately the same thickness and/or thinner than the inner band 110). The SAHR 115 may, for example, be configured to not alter or minimally alter fit of a headgear on a user's head. The SAHR 115 may be increasingly engaged (e.g., increasing coefficient of friction) as a force is applied to the cap which urges a portion of the crown provided with the SAHR 115 against a user's head.

For example, in various embodiments a force required to remove the hat may be characterized as F_(friction)=μ*F_(normal), where μ is a coefficient of friction (e.g., of the engaging region 130 and/or a user's head portion such as skin of the forehead), F_(normal) is a normal force, and F_(friction) is the ensuing force required to overcome friction. In various configurations, F_(normal) may, for example, be increased by a force applied to the cap (e.g., by wind). In an illustrative example, a user may wear a hat in a position such that an engaging region of a SAHR 115 is in contact with skin of the user's forehead (e.g., the headwear 105 and SAHR 115 as disclosed with reference to FIGS. 1A-2B with the visor 120 oriented over the user's face). The user may encounter, for example, stiff wind blowing into the user's face which, accordingly, acts to increase F_(normal) (e.g., pressing the cap against the user's head). Without an SAHR 115, the wind may urge the hat off the user's head (e.g., by slipping up a slope of the user's forehead and/or by inducing uplift of the brim). With an SAHR 115 in a deployed mode, the increased F_(normal) may increase F_(friction), effectively increasing the resistance to removal of the hat from the user's head as the wind increases. Accordingly, the SAHR 115 may advantageously increase retention (increase resistance to removal of the headgear) as adverse conditions increase.

In various embodiments the SAHR 115 may be relatively thick (e.g., thicker and/or significantly thicker than the inner band 110). in various embodiments the SAHR 115 may have a non-uniform thickness profile (e.g., thicker in the middle, thicker on at least one edge, continuously varying laterally and/or longitudinally, patterned). In various embodiments, by way of example and not limitation, the thickness profile may be configured to optimize fit and/or engagement for a specific headwear, for a specific head shape, for a specific user, or some combination thereof.

In various embodiments, for example, a relatively thick (e.g., in some embodiments greater than one-eighth inch) SAHR 115 may advantageously increase retention during sudden movements by differential shear deformation and/or elongation. In an illustrative example, a user wearing a hat with an SAHR 115 in a deployed mode may jump. The hat may, thus, experience sudden acceleration relative to the user's head. At least an engaging region 130 of the SAHR 115 may undergo (elastic) shear deformation such that a surface engaging the user's head (e.g., skin of the forehead) may undergo differential motion relative to a surface engaging the hat. The SAHR 115 may undergo (elastic) elongation (e.g., stretching). Accordingly, the SAHR 115 may, thereby (e.g., due to elongation, shear deformation), may ‘dampen’ a rate of stress applied to the hat. For example, a profile of a (first) derivative of velocity of the hat may accordingly be flatter than a profile of a (first) derivative of velocity of the user's head over a given period of time.

As depicted, the SAHR 115 is configured with a substantially rectangular shape. In various embodiments the SAHR 115 may be configured with various shapes and/or edge profiles. For example, a free edge (e.g., lower edge) of the SAHR 115 may be lobular, scalloped, serrated, otherwise patterned and/or profiled, or some combination thereof. In various embodiments the SAHR 115 may include cutouts and/or layered features (e.g., decals, patches). In various embodiments the SAHR 115 may include ornamental features such as, by way of example and not limitation, printing, stitching, apertures, patterns, textures, or some combination thereof. In various embodiments the SAHR 115 may be continuous (e.g., as shown) or discontinuous (e.g., multiple pieces).

FIG. 3A depicts a cross-section view of an exemplary SAHR 115. FIG. 3B depicts a cross-section view of the exemplary SAHR 115 of FIG. 3A. In the depicted example, the coupling region 125 is secured to the crown 106 of the headwear 105 behind the inner band 110. As depicted, the engaging region 130 is configured to fold down over the coupling region 125. In a stowage mode (FIG. 3A), the engaging region 130 folds down over the coupling region 125 behind the inner band 110. In a deployed mode (FIG. 3B), the engaging region 130 folds down over the inner band 110. Various such embodiments may, for example, be advantageously deployed in visors, low profile hats, in implementations where the SAHR 115 is desired to be completely hidden from view in a stowage mode, or some combination thereof.

FIG. 4 depicts an exemplary setaceous headwear retainer (SHR) in an exemplary hat. In the depicted example 400, the headwear 105 is provided with a retaining module 405. In this example, the retaining module 405 is coupled to the inner band 110 of the headwear 105 by fasteners 410. For example, the fasteners 410 may be magnetic modules configured to couple the retaining module 405 to the headwear 105 (e.g., using mating fasteners, such as shown in dashed lines).

The fasteners 410 may, for example, be configured to releasably (e.g., selectively) couple the retaining module 405 to the headwear 105. Fasteners 410 may, for example, include snaps. In some embodiments, the fasteners 410 may include or be replaced by hook-and-loop material.

A user may, for example, (selectively) couple the retaining module 405 to the headwear 105 using the fasteners 410. In some embodiments, by way of example and not limitation, the headwear 105 may be provided with fasteners to place the retaining module 405 in a stowage mode. For example, additional fasteners and/or fastener receivers may be located in a stowage location (e.g., in the crown of the cap) corresponding to a stowage position (e.g., such that a retaining surface of the retaining module 405 does not contact the user's skin and/or head when the headwear 105 is being worn). In some embodiments, for example, the retaining module 405 may be reversible between a deployed mode (having a retaining surface facing outwards away from the headwear 105) and a stowage mode (e.g., having the retaining surface facing inwards towards the headwear 105).

The fasteners 410 may, for example, be configured to fixedly (e.g., permanently) couple the retaining module 405 to the headwear 105. In some embodiments, the fasteners 410 may be rivets. In some embodiments, the fasteners 410 may, for example, include threaded fasteners (e.g., barrel screws).

In the depicted example, the retaining module 405 is provided with a retaining surface including an array of setae 415. In some embodiments, each seta may, as depicted, have a stalk extending distally away from the retaining module 405. A distal end of an individual seta may, as depicted, be provided with an expanded cross-sectional area. In some embodiments, for example, a distal end of a seta may be formed as a mini ‘suction cup.’ The setae 415 may, for example, advantageously increase a surface arear of contact with the user's body (e.g., skin, hair).

The setae 415 may, for example, be flexible. For example, the setae 415 may be at least partially made from silicone. In some embodiments, the setae 415 may, for example, be at least partially made from polyurethane. Accordingly, the setae 415 may, for example, advantageously conform to a wearer's head.

Although various embodiments have been described with reference to the figures, other embodiments are possible. For example, although an exemplary system has been described with reference to the figures, other implementations may be deployed in other industrial, scientific, medical, commercial, and/or residential applications. In various embodiments the SAHR 115 may be applied to various headgear. Headgear may include, by way of example and not limitation, at least partially brimmed hats, caps, crowns, helmets, scarves, headbands, visors, or some combination thereof.

In some embodiments, an inner band (e.g., inner band 110, hatband, sweatband) may be secured at a top edge (e.g., towards the peak of the crown) to the headwear 105 (e.g., to the crown 106). A retaining module may, for example, be coupled to the inner band (e.g., substantially around a perimeter). Accordingly, the band may, for example, advantageously resist being ‘flipped’ down and disengaging the retaining module from the user's head accidentally (e.g., in strong wind).

In some embodiments, a SAHR 115 may, for example, be hinged. For example, a SAHR may be hinged to be flipped upwards into the crown in a stowed mode. The SAHR may, for example, be configured to be flipped downwards in a deployed mode such that a retaining surface of the SAHR engages the head of the user.

In various embodiments one or more coupling regions of a SAHR 115 may be coupled to a desired section of the headgear (e.g., a crown, visor band, helmet strap). The SAHR 115 may be secured to a hat (e.g., a cap) via one or more coupling structures including, by way of example and not limitation, adhesive, stitching, rivet(s), dry adhesion structures, electrostatic charge, or some combination thereof. Securing of a coupling region 125 to a headwear 105 may be, by way of example and not limitation, permanent, semi-permanent, temporary, or some combination thereof (e.g., some portion permanently coupled, and some portion temporarily coupled). In some embodiments, by way of example and not limitation, an SAHR 115 may be coupled (e.g., stitched, riveted) to an inner layer of a hat (e.g., a liner) so that the fastening structure(s) is not visible on an exterior of the hat.

In various embodiments, a SAHR 115 may be coupled to a crown 106 (e.g., as disclosed with reference to FIGS. 1A-3B). In various embodiments one or more SAHRs 115 may be coupled to other portions of a headgear such as, by way of example and not limitation, sides and/or rear of a crown and/or head encircling structure. Various embodiments may, for example, have multiple SAHRs 115 which may be connected, independent, or some combination thereof. Accordingly, various such embodiments may advantageously allow a user to selectively activate SAHR(s) 115 in various portions of a headgear as desired by a user. For example, such embodiments may advantageously allow a user to re-orient a headgear (e.g., a cap or other hat). A user wearing a ball cap equipped with at least one SAHR 115 having independently selectively activated engaging regions 130 in the front and back, for example, may advantageously be able to activate at least one engaging region 130 in a front of the cap when wearing the cap forwards (with the bill over the face), and may be able to activate at least one engaging region 130 in a rear of the cap when wearing the cap backwards (with the bill over the neck).

In various embodiments a coupling region(s) 125 and an engaging region(s) 130 may, by way of example and not limitation, be a unitary body (e.g., formed as a single, contiguous piece), be assembled of separate components, or some combination thereof. For example, in some embodiments the coupling region and the engaging region may be of different materials. In various embodiments the coupling region and the engaging region may, by way of example and not limitation, be adhered together, sewed together, snapped and/or slid together (e.g., using mating features), otherwise mechanically joined, otherwise chemically joined, or some combination thereof.

In various embodiments a SAHR kit may be provided for application to a hat. For example, a kit may include at least one SAHR 115 having at least one coupling region 125 and at least one engaging region 130. A coupling region 125 may be provided with one or more structures for releasably or permanently securing the coupling region 125 to a headgear. The structures may, by way of example and not limitation, include adhesive mass(es), snaps, magnets, hooks, hook-and-loop fastener, dry adhesive mass(es), or some combination thereof. An adhesive mass may, for example, be provided with a releasable lining (e.g., ‘peel-off’) that, when removed, exposes and/or activates the adhesive mass for securing to a headgear (e.g., a crown of a hat). Accordingly, a user may, for example, advantageously apply a kit to manufacture a headgear with a SAHR 115, to retrofit a headgear with a SAHR 115, to restore a headgear with a SAHR 115, or some combination thereof.

In various embodiments a SAHR 115 may include a releasable securing mechanism (e.g., repetitive adhesive, snap, magnet, hook-and-loop type fastener) on an engaging region 130. A user may releasably secure the SAHR 115 in a specific position (e.g., in an activated mode, a stored mode). The user may operate the releasable securing mechanism, for example, to release the SAHR 115 such that the user may place the SAHR 115 in another mode. Such embodiments may advantageously retain a SAHR 115 in a user-selected mode, for example, even when an associated headgear is not on the user's head (e.g., holding a hat, waving a cap), during donning and/or removing the headgear, or some combination thereof.

In various embodiments a headgear retainer (e.g., as discussed with reference to SAHR 115) may be coupled (e.g., releasably, permanently) to an inner surface of a headgear (e.g., crown 106), an inner element (e.g., inner band 110), or some combination thereof. Accordingly, a user may have a headgear retainer readily available without operation between one mode and another. For example, a headgear retainer may be coupled (e.g., adhered, stitched, snapped, magnetically coupled) to a crown 106 and an inner band 110 at, for example, a top edge, bottom edge, side edge, therebetween, or some combination thereof. In various embodiments a headgear retainer may be coupled to an inner band 110 (e.g., adhered, stitched, snapped, magnetically coupled) at one or more locations (e.g., top edge, bottom edge, side edge, therebetween, some combination thereof). In some embodiments, for example, an inner band 110 may be coupled to an inner surface of the headgear at both a bottom edge (as depicted, for example, in FIGS. 1A-3B) and a top edge.

In an illustrative aspect, a headwear apparatus may include a crown configured to at least partially encircle a head of a wearer. The apparatus may include a headband coupled to an inner surface of the crown and configured such that it contacts the head of the wearer when the crown is operated onto the head of the wearer. The apparatus may include a retaining module. The retaining module may include a coupling region coupled to the crown. The retaining module may include an engaging region extending from the coupling region and including a retaining surface. The retaining module may be configured such that the engaging region is selectively operable between a stowed mode in which the retaining surface is substantially separated from a forehead of the wearer by the headband and a deployed mode in which the retaining surface engages the forehead of the wearer such that a coefficient of friction between the forehead and the headband is increased relative to the stowed mode.

The coupling region may be substantially disposed behind the headband. The engaging region may be releasably coupled to at least one of the headband and the crown in the deployed mode. The engaging region may be releasably coupled by at least one magnet.

The retaining surface may include silicone. The engaging region may include multiple synthetic setae extending from the engaging region such that distal ends of the synthetic setae are configured to contact the forehead in the deployed mode.

The headwear apparatus may include a bill extending substantially radially outward from at least a portion of the crown.

In an illustrative aspect, a headwear apparatus may include a retaining module. The retaining module may include a coupling region coupled to an inner surface of a headwear. The retaining module may include an engaging region extending from the coupling region and including a retaining surface. The retaining module may be configured such that the engaging region is selectively operable into a stowed mode in which the retaining surface is substantially separated from a head of a wearer by a portion of the headwear. The retaining module may be configured such that the engaging region is selectively operable into a deployed mode in which the retaining surface engages the head of the wearer such that a coefficient of friction between the head and the headwear is increased relative to the stowed mode.

The retaining module may be configured such that, in the deployed mode, the retaining surface contacts skin of the head.

The engaging region may include multiple setae extending distally from the retaining surface such that, in the deployed mode, distal ends of the plurality of setae are configured to engage the head of the wearer.

The engaging region and the coupling region may be formed from a continuous material. The engaging region and the coupling region may be releasably coupled together.

The retaining surface may be configured such that, in the deployed mode, a force applied to the headwear increases a force required to overcome friction between the head and the retaining surface and move the retaining module relative to the head.

The engaging region may extend from the coupling region such that, in the deployed mode, a force applied to lift the headwear from the head of the wearer induces a tensile force between the engaging region and the coupling region.

The engaging region may be configured to engage at least a portion of a forehead of the wearer.

The headwear may include a hat. The headwear may include a headband configured to at least partially encircle a head of the wearer. The headband may be stitched to a crown of the headwear.

A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made.
